A very light Benchmark and Simulation console program to test Hard Drives, SSD Drives, SAN Disks, HBAs, RAID Adapters & Storage Controllers. Works for any Linux, POSIX or even MS DOS or Windows system as long as there is a C compiler!Step 2: Check Disk Read Speed. To check the disk read speed using hdparm, run the following command: sudo hdparm -t /dev/sda. Replace /dev/sda with the actual device name of your storage device. This command will test the sequential read speed of your storage device and display the result in megabytes per second (MB/s).--rw= specifies if you want to a read (--rw=read) or write (--rw=write) test--size= decides how big of a test-file it should use. --size=2g may be a good choice. A file (specified with --filename=) this size will be created so you will need to have free space for it. Increasing to --size=20g or more may give a better real-world result for .

read/write; threads; latency; CPU utilization. Which blocksize will you use: If you want to read/write 1 GB from/to disk this will be quick if you do one I/O operation. But if your application needs to write in 512 byte chunks all over the harddisk in non-sequential pieces (called random I/O although it is not random) this will look differently. This will generate output that includes statistics such as the number of read and write operations per second, the amount of data read and written per second, the average number of milliseconds spent per read or write operation, etc. check disk performance with df command in Linux. We can check disk space in Linux by using the df command.
As answered above by RedEyed if you want to see read write in bytes/sec for individual processes go to setup (F2)--> Columns --> Available Columns --> Select IO_RATE (as shown in the image below) But if you want .dd: TEST Disk READ Speed. The file tempfile, that has just been created by the previous command, was cached in a buffer and its read speed is much higher then the real read speed directly from the disk.
There are many monitoring tools available to measure disk read or write speed. However suppose if we have slow disk performance and want to measure the disk read/write speed manually to confirm the disk fault, we can use below trick to identify the disk performance. 1. Identifying the disk read speed. To identify disk read speed, we have two .
